Uncontrolled inflammation and endotoxin play a central role in septic shock. Statins may possess anti-inflammatory properties, and removal of endotoxin by hemoperfusion with polymyxin B-immobilized fiber (PMX-F) could have favorable effects on sepsis. We examined retrospectively whether pre-existing statin and hemoperfusion with PMX-F at the time of admission were separately and independently associated with decreased overall 28-day mortality in septic shock patients. Consecutive 173 patients with septic shock (71.2±10.7 years old, 115 male and 58 female) were included in the present study. All patients underwent a complete history and physical examination, determination of blood chemistries. Multiple stepwise regression analysis revealed that albumin, creatinine (inversely), statin use, hemoperfusion with PMX-F and HDL-cholesterol were independently correlated to 28-day survival in septic shock patients (R2=0.464). Our present study suggests that pre-existing statin use and hemoperfusion with PMX-F may separately and independently contribute to blunt the process of septic shock.

Advanced glycation end products (AGEs) and the receptor RAGE interaction is involved in nonalcoholic fatty liver disease (NAFLD). Although exogenously administered soluble RAGE (sRAGE) has been shown to block the harmful effects of AGEs in animal models, there is still controversy about the role of sRAGE in humans. We examined here which anthropometric, metabolic and clinical variables were independent correlates of sRAGE levels in NAFLD patients. The study involved 77 biopsy-proven, unmedictaed NAFLD patients (44 male and 33 female) with a mean age of 43.4±13.0 years old. We examined which anthropometric, metabolic and clinical variables, including liver steatosis and fibrosis markers, are independently associated with serum levels of sRAGE. Mean serum levels of sRAGE were 710.7±290.2 pg/mL. Univariate analysis revealed that waist circumference (inversely), hemoglobin (inversely), number of white blood cells (inversely), total-bilirubin (inversely), free fatty acid (inversely), ferritin (inversely), and HbA1c (inversely) were significantly correlated with serum levels of sRAGE. In multiple stepwise regression analysis, waist circumference (p<0.01, inversely) and hemoglobin (p<0.01, inversely) were independently associated with serum levels of sRAGE (R2=0.176). The present study reveals that low serum levels of sRAGE are independently associated with waist circumference and hemoglobin in patients with NAFLD.
